I'd have gritted my teeth at that one, too, Cathy! It's wrong. It's just wrong. School should not teach incorrect grammar. Period. You weren't wrong if you were gentle with your correction.

I was often tempted to get out a red pen and mark up wrong stuff that came home from school before sending it back. I never had the nerve to do it, but boy, did I ever want to! smile

I'll be sitting right beside you at Grammarians Anonymous!
